While there are still other cameras in its class with marginally higher resolution, marginally better high ISO performance, more advanced AF, faster performance, better weather sealing and more solid build quality - and the Sony A900's built-in anti-shake remains unique in the full frame arena - the 5D Mark II is certainly one of the best value for money propositions on the market for image quality - especially in RAW, where you really can see the benefit of all 21 million pixels.
